There's one major difference between Costco food courts in the US and South Korea — and it's not the menu

From the outside, Costco locations in South Korea look pretty similar to those in the US. They're towering buildings, stuffed with products sold in bulk. Even the food courts are almost identical, serving hot dogs, pizza, and soft-serve ice cream.

However, scrolling through photos taken in Korean Costcos reveal a key difference: Customers are eating an incredible amount of the free onions that are provided in American stores as a hot dog topping.

Costco customers in South Korea eat 20 times as many onions as American Costco cafe customers, the Los Angeles Times reported, citing company data. The 13 Costco locations in South Korea go through more than 200 tons of onions a year.

While the figure seems impossibly high at first, scrolling through photos taken at Costcos across South Korea reveals the dominance of onions in the store's cafes:

From bulk goods to the Kirkland brand, Costco locations in South Korea are almost indistinguishable from their American counterparts.

In the cafe, the menu seems pretty similar as well — and yes, Costco does sell sushi in the US.

But, then there's the onion.

Some people just have a couple of spoonfuls alongside their pizza.

Others are eating an entire plateful.

Customers top the onions with mustard and ketchup.

Others have a plate of onions, and then add some more on their hot dogs.
